  • Ability to build VMs of all systems and implement integration tests
    • Staging VMs for ad-hoc testing
  • All servers set up with following services:
    • Git server
    • Chat app
    • Network shares
    • Federation with ActivityPub
    • Wakapi
  • Add a way to define services per host and refer to them by hostname

Modules

The nixosModules and homeModules exposed by this flake are slightly out of the norm.

Option declarations for user specific configuration are kept to:

• homeModules for CLI
• nixosModules for desktop

System configurations, to this end, should include the window manager, lockscreen, terminal etc. for that system.

These desktop programs will be configured in home-manager for each user, but those configurations consult the osConfig variable passed in by home-manager.

System Setup

The following files are required for system activation:

• /persist/home/${mainUser}/.ssh/id_ed25519

This private key will be used by sops-nix to decrypt the secrets in this encrypted file. The secrets inside the yaml file should also be set, or otherwise removed alongside their declarations , found here and references.

# On the target machine
# Boot into the NixOS installer

sudo passwd

# On the host machine
deploy --user "rafiq" --ip "10.10.0.102" --hostname "apollo"

From a Local NixOS Installer

The installation may run out of space when installing from an install ISO. In that case, use Disko to format the drives first, then create a /mnt/tmp directory and set it as TMPDIR for nixos-install.

Impermanence

System and user state is stored under /persist. Anything not declared under {environment,home}.persistence is deleted on system boot.
